// C# Example

// Builds an asset bundle from the selected objects in the project view.

// Once compiled go to "Menu" -> "Assets" and select one of the choices

// to build the Asset Bundle

using UnityEngine;

using UnityEditor;

using System.IO;

public class ExportAssetBundles {

[MenuItem("Assets/Build AssetBundle From Selection - Track dependencies")]//(包含依耐关系)

static void ExportResource () {

// Bring up save panel

string path = EditorUtility.SaveFilePanel ("Save Resource", "", "New Resource", "unity3d");

if (path.Length != 0) {

// Build the resource file from the active selection.

Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);

BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path, BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets);

Selection.objects = selection;

FileStream fs = File.Open(path+".log", FileMode.OpenOrCreate);

StreamWriter sw = new StreamWriter(fs);

sw.WriteLine("文件 " + path + " 中的内容如下：");

foreach (Object obj in Selection.objects)

{

sw.WriteLine("Name: " + obj.name + " Type:" + obj.GetType());

if (obj.GetType() == typeof(Object))

{

Debug.LogWarning("Name: " + obj.name + ", Type: " + obj.GetType() + ". 可能是unity3d不能识别的文件，可能未被打包成功");

}

/*

BuildAssetBundleOptions.CollectDependencies 包含所有依赖关系，应该是将这个物体或组件所使用的其他资源一并打包

BuildAssetBundleOptions.CompleteAssets 强制包括整个资源。例如，如果传递网格到BuildPipeline.BuildAssetBundle函数并使用CompleteAssets，它还将包括游戏物体和任意动画剪辑，在同样的资源。

应该是，下载一部分，其余一并下载

BuildAssetBundleOptions.DisableWriteTypeTree 禁用写入类型树，在资源包不包含类型信息。指定这个标识将使资源包易被脚本或Unity版本改变，但会使文件更小，更快一点加载。这个标识只影响默认包含的类型信息的平台资源包。

BuildAssetBundleOptions.DeterministicAssetBundle 确定资源包，编译资源包使用一个哈希表储存对象ID在资源包中。

这使您可以重建的资产包，并直接引用资源。当重建资源包对象，在重建之后保证有相同的ID。由于它是一个32位的哈希表空间，如果在资源包有许多对象，这将增加潜在哈希表冲突。

Unity将给出一个错误，而不在这种情况下编译。哈希表是基于资源的GUID和对象的自身ID。

DeterministicAssetBundle加载被标准资源包慢，这是因为线程后台加载API通常期望对象排序的方式，这会使读取加少寻址。

==========================================================================

改进一下，由于unity3d会自动导入新生成的*.unity3d和*.log文件，所以最好把输出目录改到Assets外面

//打包

if (id != 0)

{

string outpath = System.IO.Directory.GetCurrentDirectory() + "/unity3d-result" + path.Substring(path.IndexOf('/'));//复制文件夹结构

//string outpath = System.IO.Directory.GetCurrentDirectory() + "/unity3d-result" ;//不复制文件夹结构

if (!System.IO.Directory.Exists(outpath)) System.IO.Directory.CreateDirectory(outpath); //string outpath = path;

string str = outpath + unity3dFileName + ".unity3d";

// Build the resource file from the active selection.

BuildPipeline.BuildAssetBundle(objects[0], objects, str);

FileStream fs = File.Open(outpath + unity3dFileName + ".log", FileMode.OpenOrCreate);

StreamWriter sw = new StreamWriter(fs);

sw.WriteLine("文件 " + str + " 中的内容如下：");

foreach (Object obj in objects)

{

sw.WriteLine("Name: " + obj.name + " Type: " + obj.GetType());

if (obj.GetType() == typeof(Object))

{

Debug.LogWarning("Name: " + obj.name + ", Type: " + obj.GetType()+". 可能是unity3d不能识别的文件，可能未被打包成功");

}

}

sw.Flush();

fs.Flush();

sw.Close();

fs.Close();

Debug.Log("打包成功! " + str);

}

else

{

Debug.LogError("没有可打包的文件! 目录:" + path);

}

（可以按文件夹打包，方便提高效率）
